1. SYSTEM OVERVIEW
1.1 INTRODUCTION
Congratulations on the purchase of your new QuietCool system!
The QuietCool whole house fans dominate the market in energy efficiency and quietness. Whole house fans
operate by pulling the cool air from outside your home, through the home, into your attic, and out your attic
vents. This accomplishes a cooling effect that can save you up to 90% off your A/C related energy costs
depending on where you live. The difference between QuietCool and a standard whole house fan is a mix
between it’s astounding energy efficiency and it’s jaw-dropping sound level. A standard whole house fan
operates around 75dB; that’s equivalent to a loud vacuum cleaner running! In contrast, our QuietCool whole
house fans average at just around 45 dB; that’s equivalent to quiet conversation!
The QuietCool system uses a cutting edge, patented design to get our sound levels down to a respectable
level. Our fans suspend in the attic and use an acoustical duct that connects to a ceiling box and grille. The
result is an easy installation and quiet operation.
Once the air outside is cooler than the indoor air, crack open a few windows, turn your QuietCool on, and
enjoy the hot air being sucked out of your home and pushed out of your attic with a nice, cool breeze. While
performing 15-22 complete air exchanges per hour, the QuietCool whole house fan system will force the hot
stale air out of the attic which will help your house stay cooler during the hotter hours of the next day!

2. INSTALLATION
2.1 Installing QuietCool
NOTE: Be sure to plug in your fan before
attempting to install to ensure that the fan
is operational. If the fan is not operational,
call the company that you purchased the fan
from and request an exchange.
Installing the QuietCool system is very easy.
Simply follow the steps given below:
1. Determine from down below in which areas you would
like to install your QuietCool fans. Go up into the attic
to mark the exact location for each fan. Take the
cardboard cut-out template and a small screwdriver
with you. Make sure the template fits between the framing.
The rough opening size varies depending on which model
of QuietCool fan you are installing:
QuietCool Fan Model Rough Opening
ES-1500 14-1/4” x 14-1/4”
ES-2250 14 1/4” x 18-1/4”
ES-3100 14 1/4” x 22 1/4”
ES-4700 14 1/4” x 30 1/4”
ES-6400 14-1/4” x 36-1/4”
2. When you have chosen your exact spot, place the
template on the spot and mark it at each corner by
pushing the screwdriver through at each corner to
make a hole so that you can find it from below.

3. From below, place the cut-out template on the ceiling
at each location, making sure that you have at least
2 inches of clearance all around it. While holding the
template in place, mark its outline with a pencil.
NOTE: Repeat these steps at each location.
4. Using a drywall saw or similar device, cut out the hole
in the ceiling.
NOTE: Repeat these steps at each location.
5. Open and unpack each QuietCool fan. Take the main
assembly, which includes the motor housing, damper
box, and duct into the attic through the crawl hole
and move into position near the ceiling cut-out hole.

5
1-888-QUIETCOOL
6. Hang the motor head from the rafters by fastening the
metal strapping that is attached to the motor head to
the rafters with the wood screws. Make sure the power
box on the moter head is at the very top. Secure duct
to damper box using three black sharp screws. Make
sure the duct has a gentle 90 degree bend to help
reduce noise level.
NOTE: Once all of the QuietCool fans are hung,
it’s time to go below and install the ceiling box
and ceiling grill at each intake location.
7. Look through the hole and make sure there are no
kinks or twists in the ducting. Pull the damper box
down through the hole in the ceiling. Fasten the
damper box to either the drywall or the joist in the
attic. While holding it in place, install a 1-3/8” drywall
screw through the drywall into the flange of the
damper box on each side to temporarily hold the
box in place. Remove ceiling grille and screws from
its packaging. Center the grille over the damper box.
Install the grille with the white screws provided by
screwing through the flange of the damper box. Some
ceiling surfaces are uneven and may cause a small
gap to be present. This can easily be caulked later if
excessive.
NOTE: Repeat these steps at each location.
Always fasten the damper box to the joist in
the attic!
8. Return to the attic and go to each location. Using
the nylon straps and the long wood screws provided,
support the duct to the framing. This will stabilize
the entire assembly. Replace any insulation that was
removed. The installation of the fan is now complete.

QUIETCOOLSYSTEMS.COM
VERY IMPORTANT: Make sure the fan blade spins freely.
This is very important to system operation
NOTE: Local building codes and standards must be
adhered to in the installation of this unit.
AVOID BACK DRAFTS: Care should be taken to avoid
back drafting combustion appliances that are installed
in the conditioned space. It is strongly recommended
that combustion appliances NOT be installed in such a manner that they use room air for
combustion. Whole house fans are capable of pulling large quantities of air, from the home
and particularly if not enough windows are open. This could easily back draft gas appliances
located inside your home.
3. WIRING
NOTE: Wiring Diagrams are for examples only and wiring should be done by an experienced
electrician!

4. SYSTEM OPERATING INSTRUCTIONS
4.1 When to Run the QuietCool Whole House Fans
Anytime it is cooler outside than the inside of your home, the system will work effectively. In the summer this
normally happens in the late afternoon to early evening, through to the next morning. We recommend running
your fan through the evening. If you have a multi-speed fan, you will get the best cooling effect when you turn
the fan on low after desired cooling occurs and let it run throughout the night.
4.2 Where to Start Cooling the Home
We recommend cooling the area where you are going to be spending the most time for the next few hours.
For example, in most family situations, the early evening is spent in the kitchen or family room area. Assuming
this to be true, this is where you would want to start the cooling process.
Begin by opening a few windows in the area you are going to be spending your time and turn on all of your
QuietCool fans at once, for maximum cooling. The cooler air outside will immediately begin to create a breeze
in the home making you feel up to 10 degrees cooler, instantly. Opening windows too wide or opening too
many windows will lessen the cooling breeze you feel.
The breeze will flow through your home and make its way to each QuietCool you have in operation.
As it gets later in the evening, and even cooler outside, you can begin to open windows in other rooms of your
home, to prepare for bedtime. Then when it’s time for bed, you should close all the windows in your main living
space, but leave the windows in your occupied bedrooms open. This will provide each room with a cool breeze
as long as desired. If you are using an 8 hour timer, you can automate your fan and have it turn off when
you anticipate it being comfortable for sleeping. If you have a QuietCool installed in each bedroom as we
recommend, you can enjoy the breeze and your privacy with your door closed.
4.3 Indoor Air Quality
You will want to ventilate your home on a regular basis. Many studies show that the air inside the homes in
the United States are more polluted than the air outside. This is generally true even in the smoggiest of cities.
Your QuietCool system can greatly reduce this problem by bringing in fresh air and exhausting stale polluted
air all year round.
If you have any trouble installing or operating your new QuietCool whole house fan, please visit our website
at www.QuietCoolSystems.com for support or call us at 951-325-6340.
Quiet Cool is proudly designed and built in California.
